What an incredible way to prepare this is genuinely one of the most thoughtful and disciplined training simulations I've come across. The way you broke down the marathon into quarter segments and matched the climbs to Jungfrau's elevation profile shows such a deep respect for the challenge ahead. Creating your own aid station with the car, timing the nutrition down to 20-minute intervals, and even testing how your body responds to powerhiking versus running at different gradients that's not just training, that's strategizing. And doing all of this in the Netherlands, where the terrain doesn't exactly hand you mountains on a silver platter? That takes serious creativity and commitment.

Also, huge respect for pushing through when that blister showed up at 25km and the mud made every climb slippery. The mental game of just focusing on one climb at a time is exactly what will carry you through in September. It sounds like you learned exactly what you set out to learn how to distribute energy, when to switch to powerhiking, and what your body needs to keep going. That sense of "we did it" at the end, even knowing the next few days might bring some soreness, is the sign of a run that mattered. September is lucky to have you showing up this prepared. Keep crushing it! 💪🏔️🏃‍♂️
